Albert E. Roberts's 1870 School Desk and Seat Patent Model

Description
Albert E. Roberts from Des Moines, Iowa received a U.S. patent for an improved school desk hinge. Patent no. 107724 was issued on September 27, 1870.
This model is made of wood and has a desk attached to the back of the backrest. There is a design cut out on the front legs and a small storage space under the desk. The seat folds up for compatibility. Albert Roberts considered his September 1870 model an improvement on previous models because it strengthened the hinge joints and provided a "means of regulating the friction of the joints." The cover of the joint would specifically "receive, conceal, and protect the end of the screw bolt" making it less likely to loosen.
Albert E. Roberts was born in 1842 and became a manufacturer of school furniture.
